Drill Injection Holes in Concrete

What happens here

Begin the concrete lifting process by drilling a series of small, 5/8-inch holes into the concrete slab. These smaller holes are preferred over the larger 1 5/8-inch holes used in traditional slab jacking, as they are less intrusive and reduce the risk of cracking the concrete. The demonstration uses a Hilti brand rotary hammer drill for this task, emphasizing its efficiency in creating clean, precise holes through the concrete.

Goal: Create precise, small-diameter holes in the concrete slab for foam injection.
